Chris, yes there´s plenty...Quirós for example, one of the best crags in the book has over 15 sectors, and 270 routes 170 of which are under 6c+ and there are 60 below 6a.
There´s a great mix of climbing, grades and route types. I´ll see if they´ll stick up another topo later for me...

We briefly visited the area years ago and, despite climbing a lot better than nowadays, I recall stiff grades and struggling to find enough to do. Having said that we didn't have an up-to-date guidebook,

I went to Quiros a few years back after bailing from El Naranjo. It was a bit of an education as Chris implies, but the climbing is great, and there is a nice mix of grades. I'm assuming the guidebook contains some info on camping? We never found a campsite there, and the only flat bit of ground we managed to locate was under a tree high on the hillside; the locals didn't seem to mind, so long as you were prepared to admit that UK cider isn't a patch on theirs... Super friendly place, and well worth a visit.

Chris, I must admit i think the grades are fine, they're not holiday grades though - this isn't Kalymnos!!!
And as for enough to do, the point of the guide was to show what there is now. Quiros hasn't changed tons, but as I said there are 270 routes there, but Teverga (a ten minute drive) has over 400 routes and keeps growing The area is amazing...

Yes, there are a ton of new areas...I would guess probably 1200-1500 routes difference between the two...
My guide has the Desfiladero de La Hermida which isn't available anywhere else and the latest crags in Leon and well as classic such as Poo de Cabrales which don't appear in Adrados.
It's also a lot easier to follow and has routes lengths.
I think if you want a sport climbing trip you will be much much better served.

Mike and I are here now. Hats off to Richie. The guide is fantastic. Apparently it took Richie 2 and a half years to complete. The guide is very detailed, accurate and grades aren't easy. Our only problem is the weather, which is out of our control! It is absolutely beautiful here, infact it is like North Wales on a much bigger scale
